Scandiobabingtonite is a rare scandium-bearing silicate mineral belonging to the babingtonite group. Collectors typically look for it as small, dark, triclinic crystals formed in the cavities of granitic pegmatites or alpine-type veins.
Is this scandiobabingtonite?
5-step field checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch scandiobabingtonite with a known reference. Scandiobabingtonite sits at Mohs 6, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Streak: greenish black.
- 3Read the lusterHold the specimen under a strong light. Luster: vitreous.
- 4Match the color rangeCompare against the expected color range: gray.
- 5Look at form & habitCrystal system: triclinic. Typical habit: tabular crystals, prismatic.
